What causes this error? I see this in the logs,
ERROR SolarWinds.FreeTools.Logging.Logger - Invalid class
System.Management.ManagementException: Invalid class
at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode)
at HyperVLib.HyperVMonitor.GetResult(Int32 failCount)
but since I know little about WMI, I'm not sure what I need to do to fix the problem. The VM Monitor is installed on my windows 10 laptop and can connect successfully to my 2012 R2 hyper-v server.
